Secure up to 425 km of range after a diesel-to-electric upgrade and save 80% of costs? The time to transition to emission-free vehicles is now, as the current funding period ends on August 31, 2025. Act pragmatically to anticipate rising diesel prices and stricter climate regulations.

The topic briefly and concisely

The application deadline for the 80% funding for emissions-free vehicles and retrofits ends on August 31, 2025.

The conversion of existing vehicles (Diesel-to-Electric) preserves capital, avoids the loss of specialized equipment, and is an active contribution to the circular economy.

A TCO analysis (Total Cost of Ownership) shows that electric vehicles are more economical in the long run than diesel vehicles due to lower operational and energy costs.

The electrification of your commercial vehicle fleet is not a question of "if," but "when." Given rising operating costs, the CO₂ toll, and legal requirements like the EU's Clean Vehicles Directive, fleet managers are under pressure to act. However, transitioning to emissions-free vehicles need not be a complex undertaking. With the right strategy, focusing on retrofitting rather than just new purchases, you can protect investments made in expensive specialized superstructures. This article guides you through a clear 4-point plan, explains the crucial funding programs, and shows how you can sustainably reduce your fleet's total operating costs (Total Cost of Ownership).

Legal framework and funding deadlines: Why 2025 is decisive

The pressure to decarbonize commercial vehicle fleets is steadily increasing. The EU's Clean Vehicles Directive (CVD) requires public authorities to adhere to fixed quotas for clean and zero-emission vehicles in procurement. Clear target specifications already apply until the end of 2025, which will be tightened again starting in 2026. At the same time, the crucial funding round of the Federal Ministry for Digital and Transport (BMDV) is underway. Applications for the current funding period must be submitted by August 31, 2025. The program "Climate-Friendly Commercial Vehicles and Infrastructure" (KsNI) subsidizes the additional costs for procurement or retrofitting by up to 80%. This combination of regulatory pressure and attractive funding creates a unique window of opportunity for an economically sensible transition. Those who do not act now risk not only higher operating costs but also miss out on a unique investment incentive.

Your 4-point action plan for fleet electrification

A structured approach is the key to success. With this checklist, you navigate safely through the process:

  1. Conduct needs analysis: Analyze the daily driving profiles and range requirements of your current fleet. Identify vehicles whose routes can already be easily covered today with up to 500 km range, as offered by the Heero eTransporter.

  2. Check profitability (TCO): Calculate the Total Cost of Ownership. Consider not only the acquisition but also lower energy, maintenance, and toll costs, as well as current subsidies. An analysis of total operating costs often shows a clear cost advantage for electric vehicles after just a few years.

  3. Evaluate existing vehicles: Check which of your existing vehicles, especially those with expensive special conversions, are suitable for a Diesel-to-Electric conversion (DTE). This conserves resources and capital.

  4. Prepare subsidy application: Gather all necessary documents for the subsidy application. Use specialized consulting offers to speed up the process and avoid errors before the deadline of August 31, 2025.

This pragmatic approach enables a gradual and economically optimized transformation of your fleet.

Optimize funding pots: Up to 80% subsidy for vehicles and conversions

The current funding landscape in Germany is extremely attractive. The BMDV specifically supports companies and municipalities in their transition through the KsNI guidelines. The funding rates are clearly defined: you can receive up to 80% of the additional investment costs for the acquisition of a new electric commercial vehicle or for the conversion of a diesel vehicle refunded. Additionally, the necessary charging infrastructure is subsidized with up to 40% of the costs. This funding significantly lowers the entry barrier and makes the decision for zero-emission commercial vehicles a strategically wise investment. So far, funding has already been approved for thousands of vehicles within the framework of the previous funding calls. Time is of the essence, as the application deadline for the current funding period irrevocably ends on August 31, 2025. Proper preparation is crucial to fully utilize these funds.

TCO analysis: When truly cost-effective are zero-emission vehicles

The higher acquisition costs for electric vehicles are often cited as an obstacle. However, a mere consideration of the purchase price falls short. What is decisive is the Total Cost of Ownership (TCO), which includes all expenses incurred over the entire lifespan of a vehicle. Studies show that electric trucks can already be more cost-effective today than diesel models, depending on the usage profile. The key factors for this are:

  • Lower energy costs: The cost of electricity per kilometer is significantly lower than diesel costs.

  • Reduced maintenance: Electric drives have fewer wear parts, which reduces maintenance effort and costs by up to 50%.

  • Exemption from CO₂ toll: Emission-free vehicles are exempt from the CO₂-based truck toll.

  • Government subsidies: Grants of 80% significantly reduce the initial investment.

A Heero DTE-Sprinter with a range of up to 425 km often pays for itself due to these savings after just four to six years. The TCO consideration transforms the transition from a mere expense into a long-term profitable investment.

Circular economy as a strategy: Why retrofitting surpasses new purchases

The conversion of existing diesel vehicles is a central component of the circular economy and offers enormous advantages. Instead of scrapping a fully functional vehicle with an expensive special build, its lifecycle is extended through a Diesel-to-Electric conversion (DTE). This approach saves up to 2 tons of CO₂ per ton of material saved compared to new production. For municipalities, craft businesses, or logistics companies, this means: They protect their original investment while acting sustainably. A converted Sprinter retains its proven construction and is equipped with a modern electric drive to be prepared for the future. Heero has perfected this process and enables conversion within a few days. This makes the electrification of existing fleets not only the most ecological but also the most economical choice.

Practicality in focus: mastering range and charging infrastructure

The concern about insufficient range is often unfounded. Modern electric commercial vehicles can cover most daily routes without issue. The HEERO Tourer for nine people, for example, achieves up to 400 km, while the eTransporter even reaches up to 500 km. The basis for this is powerful batteries, like the 110 kWh gross battery in most HEERO models. The key lies in intelligent charging planning. Most of the time, vehicles charge overnight at the depot (Depot-Charging). For on-the-go charging, the HEERO low-floor bus offers fast charging with up to 165 kW. This means the battery is charged to around 80% in about 30 minutes. The establishment of an in-house charging infrastructure is also subsidized by 40%, representing a crucial step towards independence and cost control. This ensures that electromobility becomes reliable and manageable in everyday business use.
